A torque sensor is provided which does not easily generate hysteresis in an output curve from a sensing device thereof and in which abnormality in detecting the rotational torque can therefore be prevented. An input shaft and an output shaft are connected to each other through a torsion bar. An actuator portion, having a semicircular cross sectional shape, and a stopper are, such that a predetermined interval is maintained, provided for a first mounting frame integrally formed with the input shaft. A sensing device comprising of a slide-operation-type variable resistor is secured to a second mounting frame integrally formed with the output shaft. A lever provided for the sensing device and having a circular cross sectional shape is caused to project between the actuator portion and the stopper. Moreover, the sensing device includes a restoring spring for urging the lever in one direction so that the elasticity of the restoring spring realizes point contact between the actuator portion and the lever;
